Other comments above about this line mention that Dr. Gaines is using Christianity to justify enslaving other human beings. This is true. But a key phrase here is "I regard". He sees these slaves as a gift to him, from God, because the type of Christianity being employed here is the same Christianity that pardoned the crusades, Spanish acquisitions, the forced assimilation of Native Americans, etc, etc, etc. This type of theology deifies the thoughts of privileged men, pardoning any selfish desires and using spirituality (something valued by African Americans) to conquer and own them.

Watching this home burn away, though this reads sadly, feels like hope. Gardis is being released from her inherited identity as a daughter of the Old South.

An insult used by white Southerners toward Northerners who moved to the South during the Reconstruction era. Their suitcases tended to be made of a cheap carpet material, thus the name. Some of these newcomers were opportunistic; taking advantage of fragile systems. Some were idealistic, hoping to help rebuild and work alongside newly freed African Americans.

So many dashes! There are, by my best estimate, 113 em dashes used in this piece. I noticed the frequency immediately, and I think this is an intentional syntactic choice made by Poe to convey psychological instability. These dashes indicate anxiety, interruptions mid sentence, and fragmentation.
